To all 'whom it may con'cem:

Be it lrnown that 1, WILLIAM'DAYTON FREDRICK, a .citizen of the United States, residing in Bridgeton, himberland county, New `Tersey, have invented certain'lmprovenients in Blow-Heads for: Glass- Blowing Machinedl owhich the following is a specification.

My inventionrelates to glass-blowing machines, and

. consists of an impro-ved blow pipe'and` blow-headfrom and the initial means for operating the blow-head controlling mechanism are thrown. into action by one ofthe moving elements of such machine, as will more fully appear' hereinafter. I

My invention is fully shown inthe accompanying drawings, in which:

upper end of the blow-head pipe or stemand through said piston, the position and action of the blowhead.

l The blow-headl is supportedA by a hollow blow-pipe or stern 16 having a central bore 17, and this stem is provided at its upper end with a piston 1S, adapted to :i cylinder 19 carried -by the rzune of the machine. The blow-'pipe o1' stern 16 is supported in allnemcnt with the i molds 20, when the latter are brought to the blowing position, by-means oi a bearing 2l, carried by a bracket, 22',- mounted on the frame of the machine; suoli rod or stem being provided with acollar 23 to contact with the bearing A'21 andlirnit its downward movemeiit. To

the lower endof the blow-pipe or stem a discharge end i 24 is connected, which is arranged to enter the neck of. the bottle blanlgor otherarticle Within the mold to l discharge the air into the saule, and carried by this end of the stem; is the blow-head 15 :which is practically a valvecontrolling the discharge (1f-pressure through the end 240i saidstern. By having the discharge end of Athe blow-'pipe below themouth of the bottle, there is no i danger of chilling'the pressed portion of the `glass by the.' ai'r ventering' the glass-to blow .the same. 'This blow? -head lcomprises-a cupped member having a smooth Aunder surface .26 arranged'to engage the upper surface -o tli'e mold shell. This head is 'movable on the end of ,the blow pipel or stem,` being loosely mounted thereon, l and actedupononly thesiprcejof gravity. The up- -ward movement of the-blow-head is limited by the shoulder-27, andthe -erid 24 provided with an" en-` larged portion in 'which are carried passages for thefluid ',under pressure, suchenlarged portion serving also to' limit they downw ardimovementV of the blorif-head when with'said rod orstemis a tube or hose28, leading from ai source ofv pressure supply', and this enters the hollow bore .ofthe $011; When the stem is in .'the lowered position vwith the blow-hasards@ by Conacpwith the mold,-this.` tluidi.under.pressure may freely enter the Thebore 110i theblow pip'eor stem communicates n 'with across-passagefo in the enlarged portion of. the dischargeend 2 4, Vand the lower portion of the discharge end hasaoentral bore 31, communicating with a crosslpassage 32, a1so arranged in the enlarged portion, When :the bloW-head-is inthe lowered position, free frornthe mold, sshown in Fig 3, the cross-passages -30 and 32 are .closed by the. internal walll oi the same. The blowhead, however, -is provided with a chamber 33, formed I by an -internal'ann'ular groove 34 and when the blow pipe is dropped so as to cause the blowhead to engagel a mold, the movement of the blow-head is arrested and thejblowpipe or: stemcantinuiug en down, the dis 'charge end 24 ofthe same projects into the bottle lil-.inici i I orfotherartile'within thomold und in this new posiess,

tion, the cross-passages and 32 are brought into cornmunication with the chamber 33, and the liu id pressure Within the bore ofthe blow-pipe or stein pusscshthrough the same, and thence through the bore 3l to the bottle or other blank. y

The b low pipe or stein carries at its upper end a piston 18 whic11=I have noted as being within a cylinder 19. This piston is loweredto cause the blow-head to engage the mold pr 4 'ire-acting upon the upper sur face of the same. .This pressure is directed to the cylinder from pipe inwhich such pressure is constant, but which is cut ofi from the pistonl at regularinteryvals bythe action of the secondary valve 2. This valve 4s mounted in a casing 36 adjacent to the. cylinderlQ, and pressure for operating this valve is'controlled 'by' the primary valve l'operated at regular intervals by a moving part ofthe rnachineas before described.

The valve 2 comprises a' cylindrical body7` having a reduced portieri 4l at the bot-torn and an enlarged por- 'tion'42 at the top and contains the passages' 43, 44 and 45, Pressure to niovethis valve enters through the pipe 10 which communicates with the lower part of the valve casing in line with said'valve structure. Wit-hin Athe passage"43 of the valve, which is arranged for the .'mount a check valve 46, 4which is adjustable so as to passage of part of the pressure operating the valve, I

' when said pressure has accomplished the Work for which it was intended. Thevalve 2 in its new position brings the passage lleading to the upper'surface. of the piston 18, in line with the passage 49 admitting Vpressure to act on said pist-on and this pressure lowers the same and with itthe blow pipe and blow-head to ac't upon the bottle blank withinthe Inold. At this time,th e valve l admitting l,pressure to the valve 2 controlling this pis-ton 18 has been cut off, and this latter -valve'is ready to be moved to' the lower `position. This is accomplished by the' pressure -within the cylinder 47 acting upon the upper faceof the valve 2., and by reason ofthe greater area is surface, such pressure overcomes the greater esstire on theunder surface and thereby insures the droppingof thefvalve. When .this is done, the exhaust *l passage ofssa-idfvaive is brought opposite the inlet 49 to the cylinder; and the pressure above the piston is permitted to eithaust, whereupon the pressure for effecting the blowing action entering hollow bore 17 ofthe blow1 pipe or stem through. the tube o'r hose 28, acts upon the upper end of the bore oi said blow pipe' or stem and r'aises the piston to the ini-tial position.
